GREY STUDIES is a multi-disciplinary academic field that examines the biology, culture, technology, and environmental effect of the Reticulan humanoid intelligence, which abandoned human contact after the multi-Agency sneak attack on the Grey Homeworlds and "The Throwing Off" in 371 N.E.
In popular culture the field has acquired the name "Reticology".
The Cyclopedia's Director of Grey Studies is Caper Smallover.
